应用与实例

扩散体使用原则：1

由于声波在室内各反射面上连续反射，并且不断改变其传播方向，这种能使室内任一位置上的声波可以沿所有方向传播的声场称为扩散声场。严格意义上的扩散声场必须满足以下三个条件：

1. 室内的声能密度均匀，即声能密度处处相等。
2. 声能在室内各个方向传递的几率相等。
3. 从室内各个方向到达任一点的声波，其相位是无规律的。在这样的声场中，声波无论在空间位置还是传播方向上都不会一成不变地汇集在一起，而是随着传播过程的进行逐渐扩展，并分散开来，直至充满全部空间并遍及所有方向。

扩散体的特点

1. 可针对多个频段的声音进行扩散和反射
2. 可隐藏在整个影院视听室的艺术设计之中
3. 必须与吸音处理实现同步安装和测试

Diffuser To Use The Principle Of "One"

Since the the successively reflected acoustic waves in each of the reflective surfaces in the room, and changing its direction of propagation, this enables the indoor any of the waves can be in a position along all directions of propagation of the sound field is known as the diffuse sound field. The diffuse sound field in the strict sense of the following three conditions must be met:

1. the indoor acoustic energy density uniform, i.e. the acoustic energy density equal everywhere.
2. the acoustic energy is equal to the chance of passing in each direction in the room.
3. in each direction from the indoor to reach any point of the acoustic wave, the phase thereof is irregular. In such a sound field, sonic regardless of position in space Is the direction of propagation is not rigidly brought together, but gradually expanded with the conduct of the propagation and spread out, straight To fill all space and throughout all directions.

Diffusion Characteristics Of The Body:

1. for more than the band's sound diffusion and reflection
2. can be hidden among the entire theater audio-visual room of Art and Design
3. must achieve synchronization installation and testing acoustic treatment

扩散体使用原则：2

在设计布置声扩散体时，应注意以下问题： 

1. 扩散体不能同时是吸声体。
2. 扩散体应尽量采用比重大而具有一定刚度的材料，如混凝土、抹灰砖石体、大理石、花岗石等。
3. 如用木材则宜采用实心硬木，如柚木、橡木、花梨木或硬木，表面加贴多层组合板。切忌用三合板、五合板等薄板制成空心体，这样会形成对低频的强吸收。 
4. 尽可能避免用石膏浇铸扩散体，虽然制作成本很低，但它会产生金属声染色，对音色不利。
5. 扩散体各个扩散面的几何尺寸必须足以与声波波长相比，才有良好的扩散效果。      根据反射原理，一旦扩散体尺寸一定，室内声波的扩散程度随频率上升而递增。因此，在进行声扩散设计时，应注意采用大尺寸的扩散体，以增加对低音的扩散能力。

Diffuser To Use The Principle Of "Two"

Sound diffuser in the design and layout, you should pay attention to the following question:

1. diffusion body can not simultaneously absorber.
2. The diffuser should than significant and has a certain stiffness of the material, such as concrete, plaster masonry body, marble, granite.
3. If the wood is desirable solid hardwoods, such as teak, oak, rosewood or hardwood surface affixed to a multi-layer board. Avoid hollow body made of plywood, five plywood sheet, this will form a strong absorption of low frequency.
4. as much as possible to avoid the proliferation of body plaster cast, the production costs are very low, but it will produce metal coloration sound negative.
5. must be large enough compared to the acoustic wavelength, the diffusing surface of the diffuser body geometry have good diffusion effect. According to the reflection principle, once the size of the diffuser is a certain degree of indoor sound wave diffusion with increasing frequency increments. Therefore, when conducting sound diffusion design should pay attention to the large size of the diffuser to increase the bass diffusion capacity.

扩散体使用原则：3

房间的扩散特性好，则声音的衰减平滑，室内各处声音感觉均匀。任何凸面都有扩散声波的能力，包括斜面、曲面以及凸弧面，当需要扩散声波频率但受制于凸面大 小时，可采用扩散板进行处理。听音房间的建筑声学特性各不相同，不同物体对声音的反射和吸收也各不相同，所以为改善听音环境而进行声学处理，房间内的吸音 和扩散处理是一个十分重要的声学处理环节

Diffuser To Use The Principle Of "Three"

Good diffusion characteristics of the room, then the attenuation of the sound is smooth, uniform indoor entire sound feeling. Any convex diffusion has the ability of sound waves, slope, surface, and convex cambered, but subject to the convex size When proliferation sonic frequency diffuser plate can be used for processing. Building acoustic characteristics of the listening room of the same, different objects of reflection and absorption of sound also varies, so acoustic treatment to improve the listening environment, sound absorption and diffusion treatment room acoustic treatment is a very important link
